• Designed and launched 13+ scalable, fault-tolerant microservices and 47 REST/gRPC APIs using Go and Python (FastAPI), achieving a 40% reduction in p90 latency and 35% lower Cloud Spanner query load through schema optimization and a Valkey (Redis) caching layer. • Implemented a custom API Gateway with a gRPC-based service mesh, centralizing service-to-service authentication, authorization, rate limiting, retries, and traffic routing, reducing inter-service latency by 25% and enabling efficient horizontal scalability under peak load. • Built event-driven payment systems with Stripe webhooks, Saga pattern orchestration, and gRPC-based services; increased transactional throughput by 35% and reduced rollback scenarios. • Migrated file upload flows to GCP Signed URLs, improving speed for large files by 40% while enhancing security through scoped, time-bound access. • Consolidated fragmented repos into a production-grade monorepo while preserving history, enabling cross-service visibility, faster CI pipelines, and more reliable deployments. • Led infrastructure migration from on-prem to Google Cloud Platform (GCP) including GKE, Artifact Registry, IAM, and Spanner-backed systems; enabled 2x faster deployment and >99.9% uptime. • Integrated Valkey/Redis caching to reduce DB load and improved backend response latency by 40%. • Implemented observability stack with Prometheus, Grafana, and structured logging for proactive monitoring and incident response. • Automated CI/CD via GitLab Pipelines; reduced deployment incidents by 30% and introduced blue-green strategies for zero-downtime rollouts.

• Designed and developed a metadata ingestion pipeline using AWS Glue Crawlers triggered by AWS Lambda, with a Spring Boot–based REST API, to automate schema discovery and catalog updates for S3 data lakes, enhancing visibility and accessibility of data assets across the organization. • Provisioned scalable AWS infrastructure using Terraform to automate resource setup across multiple environments, streamlining cloud deployment and improving development workflow efficiency • Collaborated with cross-functional teams to increase test coverage from ~60% to 90%, improving code stability and release confidence.

• Authored a highly efficient Shell Script to automate seamless migration of Infrastructure from On-Premises to Cloud, resulting in 30% reduction in migration time. • Automated process of Oracle and SQL DB import increasing import efficiency by more than 40%

• Conducted comprehensive data analysis on over 10 Facebook Ad Campaigns at GlobalShala, identifying key areas for improvement. • Utilized data visualization techniques, such as bar and pie charts, to present findings clearly. • Collaborated with the Finance Team to provide data-driven insights, contributing to a potential 15% reduction in campaign costs and a 20% increase in efficiency.

• Engineered an advanced development infrastructure, utilizing Spring Boot, Angular, Docker, Jenkins, and Shell Scripting technologies, to optimize CRUD operations and enhance system scalability. • Redesigned and deployed an analytics dashboard using Spring Boot Actuator, Prometheus, and Grafana, yielding a 30% increase in system observability and maintenance responsiveness through enhanced telemetry and visualization capabilities. • Crafted Docker files and Shell Scripts to enrich and automate service monitoring workflows, driving operational efficiency improvements, evidenced by a measurable 20% reduction in manual tasks.
